64-bit Linux Running Google Gears In Firefox

by

Description and Problem:

Google Gears is a plug-in that extends your browser to create a richer platform for web applications. There are many Web applications that currently make use of Google Gears. Some of these include Google Docs, Google Reader, MySpace, Picasa, Zoho and (the reason for this post) now even WordPress. Google Gears, or simply just Gears as it is now known, not only enables offline browsing of supported sites, but it can also greatly improve the performance of these sites and web applications like WordPress. This makes working with supported web applications much nicer.

Now, my problem (and many others of you out there) has been that I am running 64-bit Ubuntu (8.04 Hardy Heron) and Google has not made a 64-bit version of their Gears software. They cite lack of time and testing resources, but my guess is it’s not that important to them since there probably aren’t too many 64-bit users out there. Luckilly for us, Gears is an open source project. This is now a prime example of the beauty of open source software, in that some really smart people created an “unofficial” patch that allows you to install and run Gears on 64-bit Linux in Firefox. In my case it’s Ubuntu and Firefox 3.x, but I have read folk that have had success with SuSE and others as well. It only took me about five minutes once I found the patch.

Here are the steps I took to get this installed, up and running:

Grab the latest version of the Gears binary that has been patched for 64bit at http://www-personal.umich.edu/~swolchok/gears/, I used this command:

wget http://www-personal.umich.edu/~swolchok/gears/gears-linux-opt-0.4.9.0.xpi

Open Firefox and choose File->Open File and browse to where you saved the file you just downloaded. It should open an install window, you want to press the “Install Now” button to start the install.

Once the install is complete, press the “Restart Firefox” button to restart Firefox and complete the installation.

Summary:

For me, upon the initial restart, I got an error about this addon not being compatible with my architecture. Despite that it seems to work fine, and I haven’t gotten any more errors since then, so I would suggest you simply ignore that error.

Lastly, go to a site that is supported, add it to Gears and enjoy! If you have any questions or comments, post ’em below.

PowerUp Your Shell With Your Profile

How about some neat-o shell tricks for everyone to play with? I figured out some neat things the other day while trying to add some functionality to my shell, specifically through scripts or the profile.  What I found was that the magic is in the profile!

Have you ever wanted to have commands that performed certain functions from quick keystrokes rather than long command lines? Of course you have, that’s why we all set aliases in our profiles like ‘ll’ instead of ‘ls -al’ and the like.  But what if you want or need more functionality than simple command shortening? That’s what I was after, more function in a smaller form.  Some way to pass variables to aliases to get more out of them. Ah, but you can’t pass variables to aliases, so we are stuck right? Wrong, that’s where the functions come in to play.

Here are some tips for getting Sun Microsystem’s Java environment up and running smoothly on Ubuntu.  This includes the JRE (Java Runtime Environment – for running Java apps) and the JDK (Java Development Kit – for creating Java apps).  It’s actually easier than you think!  Basically, add the universe repo and use synaptec.  An added advantage is that you can install updates through there too.

PERL Tip For Data In Arrays

Recently I was working on a script for log reporting.  You know, one of those handy little guys that send you some info every day helping to make sure you keep up with whatever it is that you don’t want to forget about.  Well, some of the data was in a plain old text file, and there is nothing wrong with that.  It’s easy to simply cat the file and pipe it through mailx or mutt, no fuss, no muss.
